Abstract

Objective: Infobuttons are decision support tools that offer links to information resources based on the context of the interaction between a clinician and an electronic medical record (EMR) system. The objective of this study was to explore machine learning and web usage mining methods to produce classification models for the prediction of information resources that might be relevant in a particular infobutton context. Design: Classification models were developed and evaluated with an infobutton usage dataset. The performance of the models was measured and compared with a reference implementation in a series of experiments. Measurements: Level of agreement (@k) between the models and the resources that clinicians actually used in each infobutton session. Results: The classification models performed significantly better than the reference implementation (p
